WINDMILL.

j Application led August 8, 192.5. i Seri-a1 No. 49,101.

To all whom t may concern.'

Be it known that I, Venetian L. ANDREW, a citizen of the Unite-d States, residing at Superior, in the county of Douglas and State of lVisconsin, have invented certaiiinew and useful improvements in lllindmills, of which Y the following is a specification, reference improved oiling device;

being had therein to the accompanying drawing. v n j 1 This invention relates to windmills and has special reference to a novel oiliiig system therefor. j

' The principal object of my present invention is toprovide a more efficient and practical loiling means than heretofore employed, and anotherl object is that of simplicity and iiiexpensiveness of parts.

Still otherobects and advantages of the novel construction rwill appear in the further 'description of the invention. l

Referring now tothe accompanying draw-- ing, forming part of this application, and in which like reference characters indicate like parte: y

vFigure 1 is a top plan View of a rocker arm in a windmill head equipped with my Figure 2' is 'a side elevation of Figure 1 showing a portion of the exterior ofthe oil carrying bowl of the head, and Y Figure 3 is a transverse section on theline 33, Figure 1.

1 represents the housing or bowl of the windmill head, upon one side of which the rocker arni 2 is pivotally supported as at 3, and the opposite or fiee end is attached to the pump plunger rod 4 as by the ball and socket joint indicated at 5. rlClie internal gear illustrated at 6 is common to such forni of Windmill heads, windmill shaft 7 which is provided with a suitable laterally extending bearing from the side vof the bowl 1. A pit-man indicated at 8 connects the rocking arm 2 with the internal gear 6, the free end of said arm being reciprocated by the rotary motion of the gear, and the arni in its cycle of travel is raised and lowered vertically past the uppermost circumferential edge of the gear, and when there is.oil in the bowl it is obvious that the saine will be' Carried around bot-h internally and externally on the internal gear 6.

Upon the side of the arm 2 next to the Oear G is formed a laterally projecting web a o u u I comprising the portions 9 and 10, that in-` and is rotated by the dicated at 9 having a groove or channel 11 formed therein next to the central body por,- tion of the arm and this groove extends from the oil hole 12 in the hub 13 of the pin 14 at one end to the @il hole 15 in the hub 1G at'the pivotally mounted end of the arm, so that any oil collected in this groove will, as it is swa'she'd from one end of the groove to theother, supply oil to both of said holes. djacent the oil hole 12 and offset slightly from the groove 11 is a cup-shaped recess 17, having a vertical hole l'therein for the dripping'of oil downwardly upon the lower connection of the pitman 8, the bottoni .of the recess 17 being slightly higher than the bottom of the channel 11. f

l The Aportion 10 of the laterally projecting web is stepped downwardly slightly andthe upper face of said web is comparatively flat though inclined slightly downwardly and outwardly from the body portion *of the arm, there being an oil hole 19 at the'lforv ward extremity of said upper. surface of the web into the ball bearing 5, so that some oil will be carried along in the corner between the body portion-of the arm and the web and fed to the ball bearing, but as is well known to those versed in the art, the necessity-of such oiling of the ball bearing is comparatively slight in respect to other parts of the windmill mechanism and that an over oiling of this joint is not desirable, thus the provision for caring for an excess of oil in that it will run o laterally from the surface of the web 10;

Intermediate of the upper extremity of the internal gear and the pivotal point 3 of the arm 2 and transverse the latte-r is mounted the oil scraping dipper 20, it having formed integral therewith the hooked finger 21 which forms the pivotal connec tion of the dipper with lthe body portion of the arm 2, the hole in said arin being such that the dipper may be hooked or unhooked from engagement with the arm, and the innerextremity of the linger 21 rests within the jaw like bearing 22 formed upon the upper portion of the outer edge wall 23 of the channel 11, thus forming a substantial and wide bearing for the pivotal member of the dipper 20. This dipper is substantially flat though it has a slightly dished upper siii'- face as indicated at 24E, there being a sur-y olf the dipper which leads inwardly over 'the arcuately shaped notch Q8 'formed in the upper face of the outer edge wall 23 Aot 4the channel l1 so that in the event ot' `the oil supply being 10W or the rotation of the mill being slow, oil adhering to the under side of the dipper will traverse same inwardly and downwardly into the channel l1 Vso as to insure an adequate supply of oil from the internal gear to the channel irrespeotire of change in conditions or Acircumstances as long as there is any oil whatever 'available in the windmill head.

It is apparent from the above that as the arm Q is reciproeated upwardly yand downwardly past the rotating gear G the 'same travelling in normally a. clockwise direction as viewed from Figure 2 of the drawing, and carrying oil, the dipper 2O will intermittently rest upon the upper circu'mf'eren tial face of the gear during which time oil will be scraped therefrom either into 'the `dipper or carried by the under `side thereof, thence to the channel 1l,sotl'1at'as 'the arm continues its travel up 'and `down the oil within the channel will be swashed ktrom end to end thereof thus adequately oiling all oi' the journal portions heretofore de` scribed.

Haring thus described my invention, what I claim and desire to secure 'by Letters Patent, is:

l. In combination, a windmill head including an oil bowl, a rocker arm piyotally mounted above said bowl having journal bearings operably associated therewith, an internal gear wheel within the bowl 'cooperatively connected vwith the 'rocking 'a'rn'n an oil channel longitudinallyoftthearm fand upon one side thereof, an Ioilscraping dipper pivotal'iy carried by :the 'arm v'and interinit'te'ntly engaging the outer surface of the gear Wheel 'for conveying oil therelrom into the Vchannel and thence to the journal bearings of the arm.

2. In a windmill the combination with an oil bowl in the head thereof, a rocker arm pivotally supported at one end and connected to Aa Ir'e'ciprocable rod at the other end, and a rotatable internal gear within said head for imparting motion to the rocker arm, of lan oil channel longitudinail)v of the rocker arm and at one side thereof, and a scraping dipper pirotally carried above the oil channel and intermittently contacting the ripper .smooth surface of the gea r wheel whereby oil is conveyed from the gear wheel into the channel vand thence to the pivotal connection of the arm.

S. In a windmill lubricator, a rocher arm and bearing surfaces associated "therewith, an internal gear wheel adapted to carry lubricant on the outer surface thereof, an oil conveying ltrough longitudinally of one side oli the roelier arm, a ecraping dipper pivotal'ly carried by the rocher arm above said trough and intermittently engageable with the gear wheel, eul'istantially aa and for the purpose described.

4. In a windmill lubricator, a lubritaint bowl, a lrocker arm fhaving Aa bearing aseociated therewith mounted above said bowl` a rotating oil carrying member within said bowl, a scraping dipper pirotally lmounted upon the arm intermediate ot its ends and int'ermit'ten'tly1 engageable with said rotating member, and means t'or conveying oil from said dipper to the lliearings associated with said arm.

In testimony whereof I hereunto aflix my signature.
